Power spectra including NILC-cleaned TT (left top), NILC-cleaned EE (right top), NILC-cleaned TE (left bottom), and cILC-cleaned BB (right bottom) power spectra with ℓ_max = 1500. The input CMB (solid black curves), the reconstructed CMB (blue bars), and the residual noise (orange curves) power spectra are plotted in each panel. The green curves represent the sum of the systematic and foreground residuals. For the BB spectra, the deprojection and foreground residuals are separately shown as red and purple curves, respectively. The power spectra are binned over every 30 multipoles except for the BB spectra, where a logarithm binning at ℓ > 100 was adopted for clarity.
